《苗瑶语古音构拟》是近年来苗瑶语古音研究的重要著作。但由于调查资料所限等方面的原因,致使书中的许多例字呈现空白状态。从贵州省白午苗话出发,对《苗瑶语古音构拟》中的部分例缺字进行了补正。 “Miaoyao ancient Chinese phonetic transcription” is an important work of Miao-Yao ancient relics research in recent years. However, due to the limitation of the survey materials, many of the examples in the book were left blank. Based on the white noon words in Guizhou province, some missing words in Miao - Yao ancient pronunciations were corrected.
